Improved window-sash fastener



UNITED STATES PATENT EEICE.

JACOB EBY, OF MANHEIM, PENNSYLVANIA.

IMPROVED WINDOW-SASH FASTEN EPL.

Specification forming part of Letters Patent No. 38,572, dated May 19, 1863.

To aZZ whom it may concern:

Be it known that I, J AooB EBY, ofthe borough of Manheim, inthe county of Lancaster -and State of Pennsylvania, have invented a new and Improved Combined Window-Stop and Sash-Fastener; and I do hereby declare that th'e following` is-a full and exact description thereof, reference being had to the accompanying drawings, with the letters of refer# ence marked thereon, making a part of this specification, in which- Figure lis a vertical view; Fig. 2, a perspective View; Fig. 3, a side view of the plate, spring, and thumb-catch on each, as seen behind. The front of the plate A is smooth, with an oblong slot for the projection F on the bolt to pass through. (Not shown.) Fig. 6 is the oblong square plate A, with its anges a d on each side of the oblong opening b b, the flanges for the pivot-support for holding the bolt B with the spring E. Fig. 5 shows the bolt applied to the plate for the upper sash, and Fig. 4 the bolt with its additional arm c for the lower sash.

The object of this invention is to supply a great demand for a simple article in the trade to effect a double object and save the expensive application of weights and pulleys for operating the upper and lower sash equally well, and to hold them at any desired elevation, an article also'that is not liable to get out of repair like those having spiral springs y are too apt to do. and only applicable to the lower sash. The plate A is the same for both bolts, Figs. 4 and 5. The flat spring E is affixed to it, its upper end resting on the Vprojecting arm c of the bolt B and bears no weight or strain further than the pushing in or pressing out of the bolt. This bolt B is held on a pivot between two elevated flanges or brackets, b, and above the brackets a a also acts as guides and prevents all lateral motion, the outer, a, having a notch for the arm c.

To prevent all undue strain upon the spring E by the carelessness of the carpenter in cutting out more wood than is necessary, the bolt is a little raised from the plate at its butt or lower end, so as to catch on the plate and arrest its being pressed in farther by the thumb-plate D than is necessary to clear the projecting point F from interfering with raising or lowering the sash, thus preventing all danger of straining the spring E.

Fig. 3 shows the plate A let in flush with the casing H, with wood cut out for the action of the bolt B, held by the screws s. The stile I shows a series of mortises, f l f 2, &c., into which the projecting part F of the bolt enters. The upper Inortise is cut in square above and below, as shown by fl. This effectually locks the sash and preventsit being raised, (as by a reverse arrangement on the edge ofthe upper stile it also preventsit from being lowered,) the other mortises, f 2 f 3 f 4, 85e., are beveled on the lower side on the lower sash, which will allow it to be pushed up as are the mortises in the upper sash after the first below, beveled on the upper side to allow it being pulled down, (the sash.) The bolt, arm, and thumb-plate B C D, Fig. 5, for the upper sash, are all Hush with the casing. The extra arm G for the lower-sash projects outside the :inner window-strip and is the only difference between them. These plates and bolts may be cast of brass 'or malleable iron, are light, durable, and easily applied, and by their use windows can be raised from below or lowered from above to any desired point without the expensive rope, pulley, and weight arrangement. This, I am aware, was partially accomplished by a small latch with a spiral spring, now entirely out of use in consequence of the lateral pressure on the spiral spring and their application to the lower sash only.

My combined arrangement secures a firm lock to the window and a ready adjustment at any desired point in drawing down the upper sash or in raising the lower, easily operated, neat, cheap, and durable, readily applied, and forms a new article in the trade greatly desired. There is also along, [lat spring in use without a plate, A, or bolt B, equally objectionable to those with spiral springs and catches.

I do not claim the plate, bolt, or spring, separately considered.

What I claim as my invention, and desire to secure by Letters Patent, is

The arrangement and construction of the oblong plate A, with its langes or brackets 0L a and b b attached, flat spring E, in combination with the bolt B, made and held by a pivot between b b, having either a straight arm, c, or elbowed arm, c c, with a thumbplate, I), and operated by a ilat spring, E, resting on the arm c, in the manner and for the purpose specified.
